The Graph

Graph1. Get a blank sheet of

graph paper

Graph1. Draw the Y axis 2. Draw the X axis

Graph1. Y axis 2. X axis

Graph1. On the X axis, Write

the range for the dependent variable, MA.

2. The range is 1 to 6

Graph1. On the Y axis, write

the range for the independent variable, EF in Newtons.

2. The range is from 1.0 N to 11.0 N

Graph

1. For Pulleys 1 through 5, Plot the data points as EF and MA

Do not write this data on your graph!This data will be found on the Data Table for each Pulley. 5 MAs and 5 EFs

Graph1. Plot a data point for

each pulley2. 5 pulleys, 5 data

points!

Graph1. In a nonlinear

graph, lines are not drawn dot to dot through data points.

2. For our Line of Best Fit, the nonlinear graph is drawn to fit or include some but not all data points.

3. The Line of Best Fit should show the pattern described by the data

Graph1. Line of Best Fit is a

compromise.2. To do it well you

would have to understand what it is for.

3. Make the line VERY LIGHTLY and show it to Mr. Gussin if you are unsure.

4. Do not draw beyond the last data point.
